Yeah, indeed very good guess!
But besides the obvious large number LEDs the 8 chips have pretty unique footprint - PDIP-18,
which most likely means they are LM3914
and explains the 2x jumpers on the PCB used to select 'dot' or 'bar' mode .
What still puzzles me is Why only 16 LEDs are used instead of 20 (as in LM3914 datasheet)?
Anyway... The same seller has more interesting items: Lot Oric - Microdisc - cartes électroniques - lecteur disquette.

ORIC TELESTRAT + Disc drive on eBay again. Who will guess the winning number this time? .
But more interesting are the 3-inch floppy disks - take a closer look at their labels (in description at bottom of page)....
If only it were true ... CP/M for Oric

Prices are mad, as usual... the Telestrat does not even work! And the Microdisc is probably a slave unit. And those CP/M disks...
Probably they are from an Amstrad computer and were re-used for this Oric or something... Or someone was thinking about building an external device with a Z80 just to run CP/M on the Oric, as other micros had.
